We had to do that review thing because we were getting too many duplicates, and didn't know about them unless we came across one at random. Some were with misspellings and some, like in the roses, can have multiple names. Zuzu already has the additional names listed but currently the search is not picking them up. So while it may be inconvenient for some to have to wait for a new entry to be approved before they can add a photo, it was the only way to set it up for now.
Another problem we were finding was some people added a species name to new entries so it would drop it toward the end of the genus listing and when someone did a search, they would only be looking down the list and once they get through the alphabet, it starts to list the species, and some of those also had the cultivar names attached. There were several liliums that were duplicates, for instance, one would have Lilium and so-and-so cultivar name, and another would have Lilium asiatic and the same cultivar name. I found it easiest to do a search by cultivar name now, sometimes that name is shared with roses or iris but at least that way you can see if the name exists within your genus search. Another good way is to search by genus and then click on the letter in the alphabet for cultivar names and make sure to scroll all the way through them. That will get harder though as the cultivar lists increase.
Some people also have a bit of trouble understanding the difference between genus, species and cultivar name. I cleaned a few of those up too.
